Personal experience, hearsay, unsupported rumors, famous examples, what are the best examples of "making do" with inferior, or an eclectic and seeming useless selection of parts to successfully solve a real problem? http://en.wikipedia.org/wiki/Rube_Goldberg_machine Probably one of the best known Rube Goldbergs was the CO2 scrubber rigged that saved the lives of three astronauts during the emergency on Apollo 13. I would bet that Danger, Zooby, and Wolram can name a few. I have to make one tonight by using a collecton of PVC reducers and converters and flanges etc, and some standard HEPA filters, to make a down and dirty inline air filter. It probably took me an hour walking around the hardware store to figure out how to do this with off-the-shelf items, but the real filters were backordered and I need them tomorrow. This one will be running on the ragged edge, but I think it will work. It should be noted that epoxy and PVC pipe have been a real boon for the Rube Goldberg industry.
